Configuration scope: The listed size, class, material, connection and actuation options are configuration-specific. They do not form a single universal operating envelope. Final availability, pressure-temperature rating, forging grade, heat treatment, inspection and NDE must be confirmed against the approved model datasheet and order specification.
Frequently Asked Questions
A forged-body construction is selected to meet the specified design and manufacturing route; it does not eliminate the need for material controls, heat treatment, inspection or NDE. The applicable forging grade, process route and acceptance criteria must be confirmed in the approved specification and inspection plan.
The published description identifies low flow resistance, which is consistent with the parallel-gate isolation design when fully open.
Petrochemical and power industries are the stated application fields. Actual selection must match the project operating conditions.
The product specifications include pneumatic, electric, pneumatic-hydraulic and electro-hydraulic options in addition to manual and gear operation.
Provide the service medium, operating conditions, connection, actuation requirements, quantity and project documentation.
Product Overview
This forged steel pressure-seal parallel gate valve is designed for large-size, high-pressure pipeline isolation in petrochemical and power applications. The gate travels linearly between parallel seating elements to open or isolate the flow path.
Its forged-body construction follows the specified manufacturing route, while the pressure-seal structure and low-flow-resistance design support demanding service within the approved product specification. Material controls, heat treatment, inspection and NDE remain project- and order-specific.
Engineering teams can select from the listed materials, RF/BW/RTJ connections and manual or powered actuation methods according to the pipeline and control requirements.
- Integral Forged Body: Manufactured and inspected to the approved forging, heat-treatment and NDE requirements.
- Pressure-Seal Structure: Supports the listed high-pressure operating range.
- Low Flow Resistance: Designed for efficient flow when fully open.
- Actuation Flexibility: Manual and multiple powered configurations are listed.
